ktest: Fix the month in the name of the failure directory

The Perl localtime() function returns the month starting at 0 not 1. This
caused the date produced to create the directory for saving files of a
failed run to have the month off by one.

  machine-test-useconfig-fail-20260314073628

The above happened in April, not March. The correct name should have been:

  machine-test-useconfig-fail-20260414073628

This was somewhat confusing.
